Application filed May 3,

i To all whoa/1 it may concern Be it. known that I, (inononQuinsTiANsnN, a citizenof the. United States, and a resident of Omaha,in the county of Douglas and State of Nebraska, have invented certainnew and useful Improvements in Buckles and VVrist-Straps, of whichthefollowing is a specification. My invention relates to buckles andwrist straps of the class especially adapted for use in holding a watchor like article upon the wrist. ItQis the object of my invention toprovide a simple and inexpensivebuckle especially adapted for use with atransversely corded ribbonor fabricstrap to form wristattaching meansfor a watch or the like, for use as abracelet. A further object ofmyiuvention is to rovide a buckle of this class havin specially formedmeans for engaging the ri bonor strap without injury thereto, butso asto effectually prevent slipping of the buckle relative to the ribbon,when theparts are in use. A further object of -myinvention is to providea buckle of this class which may be readily engaged with and disengagedfrom any intermediate portion of the ribbon or strap, by the use of onehand only, and without liability of dropping the watch withwhichthestrap and buckle are use(l. "A further object of my invention'isto provide a bucklejofthis class having means for effectually prevent:ing thesame from assuming a diagonal positionwith reference totheribbon, when the device is in use, and to prevent the buckle beingdisengaged from the ribbon or strap by lateral movement relativethereto, except by a deliberate act of the wearer. This application isin part a continuation of my application for watch bracelet, filed Aug.31. 1917, Serial No. 189,095.

In the accompanying drawings Figure 1 is an end view of a watch braceletformed with a buckle embodying my invention, and a ribbon arranged inaccordance therewith, Fig. 2 is a detail bottom or inner side view ofthe buckle, with a portion of the ribbon attached thereto, Fig. 3 is aplan or outer side view of thebuckle alone, Fig. 4 is a longitudinalsection of the buckle and ribbon. and Fig. 5 is a detail transversesection of the buckle on the line 5--5 of Fig. 2.

Referring to Fig. 1 of the drawings, there is illustrated a watch 6having at opposite sides thereof loops or bows 7 for connection with astrap or ribbonto attach the same in BUCKLE Ann warscr s'rfaar.

the form of a bracelet upon the wrist of the user. 1 preferably employ afabric strap or ribbon 8 which is cordedbr transversely ribbed, asindicated in Figs. 2 and ii, and oneend of said ribbon is connected inany suitable way with one of the bows 7 of the watch. The body orintermediate portion of the ribbon passes slidably through the secondbow 7, and the second end of the ribbon is formed into a loop 9 forconnection with the buckle.

Thebuckle is formed from a single plate of metal, and has a flatapproximately rectangular body-portion 10. On said body adjoining oneend thereof, which for convenience of description will be designated asthe rear end, there are rounded laterally projecting lugs 11, andbetween said lugs there is av transverse slot 12 of which the iearwardside is substantially closed by two fingers 13, the latter extendinginwardly into-the slot 12 until the second finger can enter the oppositeside of the loop, after whiclrthe loop is flattened out so as to liesmoothly in the slot 12, of which the width is substantially the same asthat of the ribbon. Obviously, the ribbon can be detached from thebuckle by crowding the loop into that end of the slot 12 adjoining thelonger finger 13, and then slipping one edge out through the openingbetween the ends of the fingers.

At the front end of the body 10 there is a transverse slot lat which isopen at one end, the front side of the slot being formed by the rearedge of a finger 15 which is joined to the body at the closed end of theslot. The front edge of the finger 15 is rounded transversely as shownin Figs. 2 and and at the rear edge of the finger there is a thinprojecting portion or lip 16 which extends partially across the slot 14.Opposite said lip 16, at the front edgeof the body 1.0 there is a secondlip 17, which projects downwardly, or inwardly with reference to theposition of the buckle when or turned inwardly as shown in Fig. 5.

The flange 18 terminates at the rear edge of the slot 14:, but theflange 19 is longer andextends past the closed end of said slot 14, thusstrengthening the connectingportion between the body 10 and the finger15.

' hen attached to the loop 9 at the end of the ribbon, the buckleprevents said loop being pulled through the how 7 of the watch, and thnsmaintains the bracelet formation, so, that after being slipped over thehand of the user there is no-possibility oi dropping thewatch whileadjusting the bracelet to it upon the wrist. The adjustment of thebracelet is readilyeffected by the use of one hand only, the operationbeing as follows: The lugs 11 at the sides of the buckle are caughtbetween the thumb and forefinger, the ribbon ispulled through thewatch-bow Tunt'il the desired tightness upon the wrist is attained,vand'the end of the finger 15 is then inserted beneath the ribbon, sothat .the latter passes into the slot 1% of the buckle. Upon releasinghold of thebuckle, the pull of the ribbon at the rear end thereofdrawsthe body down into parallelism withthe engaged portion of theribbonbody, as shown in Figs, 1 and l. When in this position the lips 16and 17 enter the transverse grooves or corrugations of the corded ribbonand effectually'prevent slipping of the ribbon through the buckle. Atthe same time the flanges 18and 19 embrace the sides of the ribbon andprevent the bucklebeing twisted to a diagonal position relative to theribbon-body.

To release the buckle, it is merely necesv sary to grasp" the same atthe lugsll, as

before, ulling the rear end of the buckle outward y until it isapproximately perpendicular to the engaged part of the ribribbon.

born and then moving the buckle laterally to withdraw the linger if)from beneath the The lugs ll greatly facilitate the release of thebuckle, by readily permitting the same to turn pivotally between thethumb and linger, when pulling the rear end of the buckle outwardly fromthe ribbon, and thus automatically turning the buckle-body to a positionat which the lips 17 and flange 18 do not interfere with the lateralreleasing movement.

Now, ha ving described my invention, what I claim and desire to secureby Letters Patent is: I

l. A buckle comprising a flat body portion having at one end means torconnection with the end of a strap, laterally extendinglugs at said endof the body, there being at the opposite end of the body a linger spacedtherefrom to form a transverse slot open at one end, strap-engaging lipsat each side of said transverse slot, and longitudinal inturned flangesat the sides of the body for the purpose described.

2. An adjustable wrist'slrap comprising a ribbon adapted to have one endattached to one of a pair of strap bows and have its other end slidablethrough the other one of such bows to form aloop. a buckle having oneend connected with said loop. the oppo site end of the buckle having atransverse slot open at one end whereby to pass trans versely over anyintermediate portion oi? the ribbon, there being fixed lips at the edgesof said slot cngageable with the ribbon to prevent relative longitudinalmovement of the buckle thereon, there being flanges at the sidesoi thebuckle adapted to embrace the sides of the ribbon when the same and thebuckle-body are in parallelism, and lugs at the sides oi the buckleadjoining the lirstnamed end thereof, for the purpose de scribed.
